How to Read Wheel Offset & Measurements
Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.
ANKUSI Engineering Expert Advice
Coupes and performance platforms are where rotational mass shows up fastest — in acceleration, in braking, and in how quickly the chassis changes direction. Forging lets us build to the same strength spec as the factory wheel at a meaningfully lower rotational weight, which is where the performance gain actually comes from, not just the visual one.
The Porsche 968 Club Sport runs a 5x130 bolt pattern, 71.6mm center bore, and a F: 17x7.5J wheel from the factory. Our Flush Fitment reference is F 17x8J ET55 / R 17x9.5J ET50, which tucks the tire under the fender lip on a stock-height Porsche 968 Club Sport. Our Maximum Aggressive reference is F 18x8.5J ET45 / R 18x9.5J ET40 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Porsche 968 Club Sport OE Wheel Specs
The 1993 Porsche 968 Club Sport (Sports Coupe) uses a 5x130 bolt pattern with a 71.6mm center bore. Factory wheels are F: 17x7.5J R: 17x9J.
Why the factory spec works for most owners:
- Keeps unsprung weight low to preserve the factory handling balance
- Matches the wider, performance-oriented tire sizing typical of this platform
- Maintains clearance for the factory brake package and suspension geometry
- Balances grip with ride comfort for daily and spirited driving
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Porsche 968 Club Sport (1993) we drill the 5x130 pattern and cut the centre bore to 71.6mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.

Real-World Fitment Notes
The Club Sport left the factory already on the 17-inch wheels that most naturally-aspirated 968 owners retrofit as an upgrade. Genuine period 968 Cup wheels are scarce and expensive today, which keeps steady demand for forged reproductions in the correct 5x130/71.6mm spec.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 17x7.5J ET65 → ~6.81″ F backspacing, R 17x9J ET55 → ~7.17″ R backspacing
- Flush: F 17x8J ET55 → ~6.67″ F backspacing, R 17x9.5J ET50 → ~7.22″ R backspacing
- Max: F 18x8.5J ET45 → ~6.52″ F backspacing, R 18x9.5J ET40 → ~6.82″ R backspacing
A Note on Clearance
Final clearance depends on the exact tire model, suspension height, brake package, alignment and vehicle tolerances. A physical test fit is recommended before production.
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Porsche spec, or want a wheel built to a custom offset for your Porsche 968 Club Sport? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Vehicles With the Same Hub as the Porsche 968 Club Sport (5x130, 71.6 mm Bore)
In our database, 294 other vehicle entries from 10 makes use exactly the same 5x130 bolt pattern and 71.6 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
5x130 is used by 5.8% of the vehicle pages in our English fitment guide (375 of 6,503); 78.7% of those also use a 71.6 mm center bore.
Hub-Centric Rings for a 71.6 mm Center Bore
A wheel with a center bore larger than 71.6 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 72.6 mm | 72.6 → 71.6 mm |
| 73.1 mm | 73.1 → 71.6 mm |
| 74.1 mm | 74.1 → 71.6 mm |
| 76.1 mm | 76.1 → 71.6 mm |
ANKUSI forged wheels are bored to exactly 71.6 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Porsche 968 Club Sport use?
The 1993 Porsche 968 Club Sport uses a 5x130 bolt pattern.
How many lug bolts does the Porsche 968 Club Sport use?
The Porsche 968 Club Sport uses a 5-lug bolt pattern (5x130), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Porsche 968 Club Sport?
The Porsche 968 Club Sport's center bore is 71.6mm. If an aftermarket wheel has a larger center bore than this, hub-centric rings are recommended so the wheel centers on the hub itself rather than relying on the lug bolts alone.
What size are the factory (stock) wheels on the Porsche 968 Club Sport?
Factory wheels on the Porsche 968 Club Sport are F: 17x7.5J R: 17x9J.
What is the biggest wheel size I can fit on my Porsche 968 Club Sport without rubbing?
The most aggressive fitment we recommend without fender work is F 18x8.5J ET45 / R 18x9.5J ET40. Going beyond this typically causes rubbing under compression unless you roll the fenders or add camber correction.
What does a flush wheel fitment look like on the Porsche 968 Club Sport?
For a flush look with minimal to no rubbing, we recommend F 17x8J ET55 / R 17x9.5J ET50 as a starting point on a stock or mildly lowered Porsche 968 Club Sport.
Do I need wheel spacers for my Porsche 968 Club Sport?
No. ANKUSI forges each wheel to your exact target offset, including the flush or max specs above, so you get the correct fitment without stacking spacers. Spacers are typically only used to push out an existing OE-offset wheel without replacing it, which isn't necessary when you're ordering a custom-offset forged wheel.
How do I calculate wheel backspacing for my Porsche 968 Club Sport?
Backspacing (in inches) = wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance). For example, the flush spec above works out to roughly 6.67" backspacing up front and 7.22" in the rear.
What's the difference between wheel offset and backspacing?
Offset is the distance in millimeters from the wheel's true centerline to its mounting face (positive offset pulls the wheel in, negative pushes it out). Backspacing is the distance in inches from the mounting face to the back edge of the wheel barrel. They describe the same fitment from two different reference points, which is why ANKUSI lists both above — some shops and tuning guides quote offset, others quote backspacing.
Can I run staggered wheels (different sizes front and rear) on my Porsche 968 Club Sport?
Yes — the Porsche 968 Club Sport's factory and our recommended flush/max fitments already use staggered sizing (different width front and rear), and ANKUSI can forge matching staggered sets to your target offsets.
